The de-facto leader of South Korea's sprawling Samsung group Lee Jae-yong went on trial Tuesday on charges of illegally using the anesthetic propofol, the latest legal travail to beset the multi-billionaire.

Lee -- the vice-chairman of the world's biggest smartphone maker Samsung Electronics and according to Forbes the world's 297th richest person -- is accused of having repeatedly taken the anesthetic at a plastic surgery clinic in Seoul in 2017 and 2018.

Dozens of drones floated through the skies of Tel Aviv on Monday, ferrying cartons of ice cream and sushi across the city in an experiment that officials hope provided a glimpse of the not-too-distant future.

Israel's National Drone Initiative, a government program, carried out the drill to prepare for a world in which large quantities of commercial deliveries will be made by drones to take pressure off highly congested urban roads. The two-year program aims to apply the capabilities of Israeli drone companies to establish a nationwide network where customers can order goods and have them delivered to pick up spots.

Facebook, in the aftermath of damning testimony that its platforms harm children, will be introducing several features including prompting teens to take a break using its photo sharing app Instagram, and "nudging" teens if they are repeatedly looking at the same content that's not conducive to their well-being.

The Menlo Park, California-based Facebook is also planning to introduce new controls for adults of teens on an optional basis so that parents or guardians can supervise what their teens are doing online. These initiatives come after Facebook announced late last month that it was pausing work on its Instagram for Kids project. But critics say the plan lacks details and they are skeptical that the new features would be effective.

Nissan's "intelligent factory" hardly has any human workers. The robots do the work, including welding and mounting. They do the paint jobs and inspect their own paint jobs.

"Up to now, people had to make production adjustments through experience, but now robots with artificial intelligence, analyzing collected data, are able to do it. The technology has developed to that level," Nissan Executive Vice President Hideyuki Sakamoto said during a tour of the production line for the Ariya sport-utility vehicle at its Tochigi plant Friday.

Facebook and its Instagram platform have wrongfully removed and suppressed content by Palestinians, including about abuses during Israeli-Palestinian violence this year, Human Rights Watch said on Friday.

Switzerland's foreign minister says concerns about a "new Cold War" over science and technology are a major reason behind the creation of a new think tank that looks out for future advances and development — so that the whole world can benefit, not just rich countries.

Ignazio Cassis delivered a video message for the inaugural "summit" on Thursday and Friday of the Geneva Science and Diplomacy Anticipator, or GESDA, a Swiss government-backed project that aims to bridge government policy and science in an international city known for both.

The six-hour outage at Facebook, Instagram and Whatsapp was a headache for many casual users but far more serious for the millions of people worldwide who rely on the social media sites to run their businesses or communicate with relatives, fellow parents, teachers or neighbors.

When all three services went dark Monday, it was a stark reminder of the power and reach of Facebook, which owns the photo-sharing and messaging apps.

Facebook along with its Instagram and WhatsApp platforms suffered a worldwide outage Monday that has extended more than three hours. Facebook's internal systems used by employees also went down. Service has not yet been restored.

A data scientist who was revealed Sunday as the Facebook whistleblower says that whenever there was a conflict between the public good and what benefited the company, the social media giant would choose its own interests.

Frances Haugen was identified in a "60 Minutes" interview Sunday as the woman who anonymously filed complaints with federal law enforcement that the company's own research shows how it magnifies hate and misinformation.

Facebook is putting a hold on the development of a kids' version of Instagram, geared toward children under 13, to address concerns that have been raised about the vulnerability of younger users.

"I still firmly believe that it's a good thing to build a version of Instagram that's designed to be safe for tweens, but we want to take the time to talk to parents and researchers and safety experts and get to more consensus about how to move forward," said Adam Mosseri, the head of Instagram, in an interview Monday on NBC's "Today" show.
